So, you should already know, that the cowlings aren’t round (however the shape is ’rounded’, but not exactly round like in T-50).

Engine conlings in the F-35 are not round.

Sorry, but had to pop-in with a comment – LOL

Ww, here’s your post:

To be more precise M1.67 with 5500lbs of ordinance(2 JDAMS and 2 AMRAAMS).

…in response to my comment on combat load of just 2 MRMs, so you were obviously trying to make a distinction.

Initially, you’ve claimed M1.67 with 5.5k lbs and wasn’t able to back that up.
Instead, you’ve presented M1.6 with 3k+ lbs and you expect to get away with that???

There’ve been numerous posts on this topic before. I’m not going to spend the effort to go look for those links everytime this debate comes up.:p
You’re correct that there is an error, but it’s with the Mach number.:cool:

Thought as much…
The trouble (for you) is there was a single source (LM) of those figures and all newsagencies transfered the same news, as the one I’ve linked.
Two JDAMs, you’ve added, are purely a product of your imagination and the attempt to make semantic point is really entertaining.

So, unless you’re ready back up your claims with something more substantial than your imagination, I’d suggest you stay out of my posting.

To be more precise M1.67 with 5500lbs of ordinance(2 JDAMS and 2 AMRAAMS).

Really?
Could you post a source for that information??

This one here, says differently.

For all you know the F-35 can reach Mach 2 as is.

Well pfcem, this is for all YOU know.
Funny thing is LM thinks differently and is explicit on M1.67.

> Mach 1.6 but most likely < Mach 2.0

Yes well, I’d expect as much from you.
You might as well said M1.6 < JSP top speed < M23 and make equal point, which is no point at all.

Sorry, been looking for something to respond to, but found nothing.

THRESHOLDS are minimums that MUST be met or exceeded.
OBJECTIVES are ‘maximums’ for which exceeding is considered as no value.
Mach 1.6 with a full internal load is a THRESHOLD, not an OBJECTIVE.

And when I said otherwise?
What you don’t seem to recognize, are difference margins between KPP and top values, for an optimized design.

It hasn’t, it has been designed for >Mach 1.6. And again, Mach 1.67 was with a full internal load for the pre weight reduction (aka ~2400 lbs heavier than post weight reduction) design.

Pfcem, for the second time, the weight doesn’t matter in terms of linear motion (top speed).

What HAS been said is that its inlets do not limit it to Mach 1.6. And no higher (or lower) Mach limited inlet would not effect the size of the weapons bays or the internal fuel capcity (the exception of course would be a totally difference VG inlet).

The inlet isn’t just the “mouth”, but the duct size and layout behind the mouth as well, which is even more important.
So, yes and if the LM designers did a good job optimizing air ducts (in size and shape) for M1.6, the plane most certainly got bigger fuel tanks and weapon bays, then it would have, if the top speed KPP was M2.

Pfcem, for the third time…
The plane (JSF, or F16) reaches it’s top speed once the overall pressure increase (total drag) equals the thrust, including pressure increase from the inlet.
JSF and F16 have different engines with different airflows producing different thrust, so inlet shape is just a (minor) factor in that pressure (drag) build-up.
This is because, F16’s F1X0 requires less airflow for the plane to fly M2 than F135 in F35 and so, while having the same pressure increase (bump), F1X0 (in F16) has less (or equal) drag to overcome, then the inlet pressure bump adds to the total drag of the F16.
F35 is something else.

To extrapolate that F35 would somehow fly M2, if just fitted with F119 (f.e.) is plain wrong.
It would take inlet/duct redesign to reach that speed, if possible at all.

It is YOU & those like you makeing the mistake. KPP (THRESHOLDS) are MINUMIMS which must be met or exceeded not, ‘do not exceed’ maximums.

Reread what I wrote…so once more, KPPs are indeed minimums, but are maximums (or just about) as well.
If F35 (and its inlet) has been designed for M1.6, it’ll do M1.67 (as disclosed), but won’t do M2.
However, if the JSF does M2 with current inlet and KPP is M1.6, then the design team did a poor job optimizing the plane and it could have larger weapon bays, or fuel tanks.

Don’t confuse JSF’s inlet installation with F16’s and both won’t do the same, although the inlet shape is similar.
